for further use in operating the scale or other description and will be particularly pointed out in the appended claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings, in which,-

Figure 1 is a vertical elevation of the inner side of the coin-controlled mechanism assembly embodying my invention, showing it in co-operation with an associated mechanism.

Figure 2is an enlarged fragmentary view of the upper end of the assembly, showing the coin at the receiving station R and operative station A.

Figure 3 is an enlarged fragmentary View of the assembly, showing the coin at the operative station B.

Figure 4 is an enlarged fragmentary view, showing the coin at operative station C and in dotted outline at the discharging station D.

Figure 5 is an enlarged fragmentary view of the outer side of the assembly showing the actuating bar in its inoperative position together with the counter and its control mechanism.

Referring to the drawings l designates a vertically disposed assembly plate having an angular upper end 2 and being attached to a base plate 3 by an angle iron 4. Mounted on the inner side 5 of the assembly plate I are two upper and lower coin shute plates 6 and l, which are held spaced from the assembly plate I by intervening spacers 8a and 9b respectively, forming thereby a. two sectioned coin shute la and H312 for a coin inserted at the upper end. In order to advance a coin CN dropping from the coin receiving shute section lDa to successive operative stations A, B and C, a plunger or push rod H (Fig. 1) is slidably mounted on the inner side 5. of the assembly plate I in a slotted outerguide member l2, extending under an inner guide plate 13 and being disposed at an angle to the uppercoin shute section lfia, with its inner end adjacent to the uppercoin shute outlet M. The inner end of the plunger l I slides between the angular edge l5 of the outer spacer 8a and a spaced lower L-shaped guide plate It, which is located below the inner guide plate I3 and is fastened with the guide plate l3 to the assembly plate I,.

thereby forming a guideway for the plunger H. v

In order toreturn the plunger H, after its operation, to its inoperative position it is provided with a retractile coiled spring H, which has its inner end'secured to the upturned tip of an offset arm l8 attached to the plunger I l, while its outer end is secured to the outer guide member l2.

A safety catch I 9 for preventing the removal of a coin dropping from the upper coin shute Illa to the receiving station R, is located below the lower end M of the coin shute and comprises a catch bar 2!], engaging and sliding, on the edge of the outer spacer 9b of the lower coin shute plate 1, the spacer 9?) being spaced back so as to form a channel 2! in which the catch bar is adapted to slide. Moreover, the catch bar 20 is provided at its upper end with a notch 22 engaging in its extended position the stop arm Ilia of the guide plate I6 and thereby limiting its upward movement, and an extended arm 23 leading therefrom and adapted to advance and engage the edge of a coin, when initially pushed by the plunger I from the first operative station A to station B. The safety catch bar 28 is alsoprovided with a retractile coiled spring 24, which has its upper end secured to an offset lateral lug extending from the lower coin shute plate I and its lower end to an angular flange 26 at the lower end of the catch bar 20, which permits the catch bar to yield and be depressed by the coin as it is advanced from the receiving station R. to the first operative station A. At the lower end of the catch bar 20 is an extended guide arm 21, which is adapted to engage a spaced stud 21a mounted in the assembly plate I, while the extended arm 23 at its upper end engages the inner edge of the lower guide plate arm [6a, by which means the catch bar 20 is guided during its entire movement.

Located at the inner side of the uppercoin shute outlet I4 and along the inclinededge 28 of the inner spacer 8a is an inclined coin guide plate 29 (Fig. 2) provided on its lower edge with two adjoining inwardly curved coin guide recesses 30 and 3|, a depending projection 29a and an intervening depending coin control projection 32, the depending projections forming the operative stations A and C, and the recesses 30 and3l forming the coin guide portions B and D, respectively, with which the coin in its travel under control of the plunger is successively engaged as will be hereinafter noted. "Pivotally mounted on the outer side 33 'of'the assembly plate I (Fig. 5) is an actuating arm 34 extending through a guide plate 35 'atits outer end and. carrying approximately midway thereof a laterally extending coin contactor stud 36 provided'with a coin contactorroller 136a, extend' ing through an inclined limit slot 31 in. the as-.

sembly plate I and beyond the opposite side thereof and carrying onitsfree, end an actuating roller'38.

The coin contactor roller 36a on the coin contactor stud 36 is engaged and depressed by the coin CN as it travels from station A to station 3-. (Figs. 3 and 4) and thereby operates the actu. ating arm 34 as hereinafter described. A retractile coiled s'pring39 is secured at one end in an opening 40 in an uprightarm 4| attached to the actuating arm 34, and at the other end to the-assembly plate I, by which means the actuating arm 34 iswithdrawn to its inoperative position as shown in Fig. -5. ,Moreover, the actu-t V ating arm 34 is also adapted during-its move:

mentto co-operate with andoperateallied mechanisms, as described in the co-pending application referred to below such for example, as a counter 42 (Fig. 5) for recording the numberof personsoperating the mechanism, The counter 4 42 is mounted above the actuating, arm 34" on the inwardly inclined arm 43 of a bracket 44, attached to the assembly plate .I and is provided with a control arm 45 pivotally connected at its upper end tothe counter actuating -arm:46'

engaging at its stroke: astop stud 4'1. The counter is operated; simultaneously by the coin; when it reaches station B at themidway stroke oithe actuating arm 34 (Fig.3). The countercal control arm 45 at its, lower end is provided with;

an elongated adjusting slot 48 co-operating with a stud 49v located at the upper end of-the uprightarm 4| carried by'the actuating arm-'34, whereby the upright arm 4L is permitted to move with the actuating arm 34 to its full'str'oke.

A 'retractile coiled spring 50 for withdrawing the counter control bar 45-to its inoperative position 5) issecured by its upper endin an opening in the control bar and has its lower end. inserted in the same opening 49 inthe upright arm'4l to which the coiled spring 39 of the actuating bar isconnected. I J 'In operating the coin-controlledmechanism a coin CN descending from the upper coins-hute Illa reaches the receivingstation -R (Fig. 2), 2 whence under urge ofthe plunger I the coin,

first engaging at station A the. outer end. de-

pending projection 29a. of the coin guide: plate 29:, pushes down the safety catch l9 and upon reaching the coin control recess 30 at station E the safety catchv is freed by the coin and under control of the retractilecoiled spring 24 it isdrawn upwardly sothat. its extended arm 23- 'will engagethe edge of the coin and thus prevent its Withdrawal. When the coin reaches. station B. also. engages the. coin contactor roller 35:;

actuatingarm 34 at stations A, B and C, under further urge of the plunger H the coin is pushed around the coin control projection 32 to the coin control recess 3| at the coin ejecting stati'on D, where the coin is freed fromthe coin contactor roller 36a, thereby releasing the actuating arm 34 and guided by the control recess 3| the coin is permitted to drop into the lower cointchute l0?) and hence to the coin'box" (not shown); I I

. The coin-controlled mechanism embodying the invention and herein described is adapted to cooperate with and actuate any suitable mechanism with which it will function, such as weighing scales and heart beat indicator scale mecha nism. Therefore, for illustrative purposes the coin-controlled mechanism is shown in the draw-" ings (Fig. 1) co-operating with and actuating,

through its actuating bar '34 the control mecha' nism of th'e'heart beat indicator scale mechanism coveredin the co-pending patent --application of Alvah B. Jacobus and Harlan A. Hadley;

:Inrthe heart beat indicator'mechanism re ferred to there is employed" an electricswitch' control member 5|, (Fig. 1) pivotally mounted y above" an electric spring: switch 52, which controls the circuit to an electric lamp (not shown) supplying the light to the lightbeam projector (not shown). 'The control member 51 is provided with a rounded lateral lug 53, anenlarged lower Weighted portion54, both extending inwardly, and at the lower end with an insulated contactor tip normally depressing, as shown.

in Fig. 1; the'lower springleaf 56 of the switch and thereby holding the switch open. The actuating arm 34 at the midway position of ,its downs I ward stroke depresses 'thelateral lug 53 of the;

control member, thereby partially raising the control member, releasing the contactor tip 55 from the lower spring leaf 56- and thus closing the circuit. At the full stroke of the actuating arm 34 the switch control member 5|. engaged by the actuating coin contactorroller 36ais raisedjhigher so that a pin 51 carried thereon is engaged by a lockingrhook 58, which holds the switch control member15| in its elevated po- 7 sition, as shown in dotted outline in- Fig; 1 while the light beam is being projected an'd the heart beat mechanism operated. -Whenthe operator steps from' the scale platform the switchc'ontml member 5| is released from the'locking .hoo|. :-..5||' by a tripping. dog'59, carried by an arm fill-corrnected to the rack rod 6|-of the indicator mech anism, and is permitted under control of the weighted. portion 54to return to its operative position (Fig. 1) depressing the-lower spring leaf 56' of the switch and thereby shutting oif the current to the electric lamp- 'of the projection mechanism (not shown).

While I have shown .a. preferred embodiment;

of-my invention. itis evident that modification of the inventionmay be-made that will come-f i within the scope thereof and, therefore, I do not desire to limit the invention to the exact form of construction shown and described herein.
